Why is this not a draw?

ProfDrHack- "Why do people think that the rules of one single country should have greater weight in internet chess (by definition international) than the official world-wide rules?"

-That argument is flawed. It's about which rules make the most sense. What if the international rules stated that that all left handed boys get an extra queen? Would that be fair? In this instance Sarg0n and Toadofsky pointed out that the FIDE (international) rules make more sense than USCF rules. Being from the US and playing on a different site, I was surprised when my opponent won with just a bishop because that's not what I was used to, but on reflection, the FIDE rules make more sense. He could have won with a helpmate.

Someone replied again that uscf rules state that a bishop is a draw even if there is a forced mate.

"US Chess rule 14E (insuffient material to win on time) specifies cases where the game is drawn even if one player runs out of time. One of the cases listed in rule 14E is the opponent having only a king and knight (and not having a forced win)."

I'm pretty sure any arbiter will rule a win if forced mate is easily calculated on the board. (unless they have it in their heads that the rules state it is a draw regardless which i don't think is true, what i've found states the exception of forced mate.)

Here is some possible mates from the position your opponent had. By under promoting to either a knight or bishop a mate can be made.
